I have been hearing for the last 3-4 years that the market is going to drop. Sort of like predicting the long range weather, keep saying the same thing long enough and sooner or later you will be right.
IMO, overall the musclecar hobby will continue to flourish. Yes, some of the crazy stuff may falter, but the quality, hi-performance cars will continue to appreciate. Maybe not at the rate they have the past few years, but will continue to draw attention, thus $$$.
I say this because of the interest in the cars, especially supercars right now. I visit with media folks, vendors, show promoters and collectors on a dailey basis and can honestly say the interest in rare musclecars is increasing, not decreasing. Just look at what is happening in the magazines, with almost ever automotive magazine featuring an older musclecar or two each month. Major shows are catering to the older musclecars more and more. The collectable market, which is driven by the interest in the cars and the folks who built/designed them, is becoming big business. Just look at the sYc and the SCR, where growth the last couple of years has been overwhelming, with new folks jumping on board dailey.
Yes, as the stock market recovers, we will see some folks move on to other investments/trends, but in large part the baby boomers will continue to relive, through musclecars, a more simply, and enjoyable part of their past.
At least I will.
